The article deals with the preliminary evaluation of the efficacy of a group intervention program composed by divorced parents, named Pais Por Inteiro (PApi), which was implemented with the aim of improving adjustment to divorce, coparenting relationship and family binuclearity. Participants (n = 16) were equally distributed in an experimental group (subject to intervention) and a control group. Groups were similar in pre-intervention dependent measures. The results showed an improvement between preand post-test in adjustment to divorce and coparental quality in the experimental group, and an improvement in post-test in adjustment in the experimental group. Those improvements did not exist in the control group. The results suggest the efficacy of PApi in terms of better post-divorce adjustment and coparental relations.
